Retinal artery occlusion in young patients without typical cardiovascular risk factors: etiologies, prognosis, and suggested work-up.

Purpose: To understand the etiology, work-up, and secondary systemic and ocular events of retinal artery occlusion (RAO) in young patients (≤ 45 years old) without typical cardiovascular risk factors.

Methods: Retrospective longitudinal case series of 18 young patients with RAO and without typical cardiovascular risk factors evaluated at the University of Michigan Medicine Health System between the year 2000 and 2022. Laboratory and imaging studies performed at the time of RAO diagnosis, along with systemic and ocular events during follow-up, were recorded.

Demographics, Risk Factors, and Etiology of Posterior Cerebral Artery Stroke Causing Homonymous Hemianopia.

Background: Posterior cerebral artery (PCA) strokes account for up to 10% of all ischemic strokes, often presenting with homonymous hemianopia. The proportion of these strokes attributed to various etiologies varies widely in previously published studies, owing largely to differing patient populations, definitions of stroke pathogenesis, and vascular territories involved. The Causative Classification System (CCS), an automated version of the Stop Stroke Study (SSS) Trial of Org 10,172 in Acute Stroke Treatment (TOAST) system, allows for a more rigorous assignment of stroke etiology.

Presenting Symptoms and Imaging Features of Posterior Cerebral Artery Stroke Causing Homonymous Hemianopia.

Background: Posterior cerebral artery (PCA) stroke is a common cause of homonymous hemianopia and other neurologic deficits associated with more proximal ischemia in the vertebrobasilar circuit. Localization of the process can be challenging unless the symptom complex is well recognized, yet early diagnosis is critical to forestall dangerous driving and repeated stroke. We undertook this study to provide additional detail about the presenting symptoms and signs and their correlation with imaging abnormalities and stroke etiology.

The Clinical Impact of Implementation of a Multidisciplinary Endocarditis Team.

Background: Infectious endocarditis is associated with substantial in-hospital mortality of 15%-20%. Effective management requires coordination between multiple medical and surgical subspecialties, which can often lead to disjointed care. Previous European studies have identified multidisciplinary endocarditis teams as a tool for reducing endocarditis mortality.

Preeclampsia, eclampsia, and posterior reversible encephalopathy syndrome.

Preeclampsia is a disorder of pregnancy associated with gestational hypertension and end-organ dysfunction. Patients with eclampsia, by definition, have seizures as part of the clinical syndrome. However, patients with preeclampsia can also have other neurologic symptoms and deficits.

Physician perceptions of a multidisciplinary endocarditis team.

Infectious endocarditis is a highly morbid infection that requires coordination of care across medical and surgical specialties, often through the use of a multidisciplinary team model. Multiple studies have demonstrated that such conferences can improve clinical outcomes. However, little is known about physicians' impressions of these groups.

Ethical Issues in Vascular Neurology.

There are ethical aspects to each of the three phases of cerebrovascular disease: hyperacute management, acute prognostication and management of early complications, and long-term recovery and reintegration with the community. This article addresses ethical concerns pertinent to each phase. First, we discuss ethical issues regarding consent for thrombolysis and endovascular treatment for acute ischemic stroke, including a review of considerations regarding the provision of acute stroke treatment advice over the telephone.
